AbstractThe switching apparatus is intended to be used with a segment of an electric power line having several phase lines. Each of the phase lines has several conductors electrically insulated one from the other and connected in parallel. The conductors of each phase line are short-circuited among them at two extremities of the segment. The apparatus comprises pairs of switches connected in parallel, for selectively opening and closing the conductors of each phase line, a detecting device for detecting current operating conditions of the segment, and a controlling device for controlling the pairs of switches according to the current operating conditions of the segment. The present invention also relates to a switching method.
